Description. Male. Body length about 1.09 mm (N=01). Wing length about 1.52 mm (N=01). Terminalia ( Fig. 8 ). Gonocoxite longer than wide. Gonostylus long and thin, with apical tooth. Cerci as long as hypoproct. Hypoproct microtrichia-covered, with spiniform microtrichia ventrobasally, with two lateral, cylindrical lobes covered with spiniform microtrichia throughout, continuing as a dorsoventrally flattened, apically bilobed lamella, with deep and wide emargination and a prominent seta on each lobe. Hypoproct about half length of aedeagus. Mediobasal lobe of gonocoxite elongated, divided at base, apex bearing few setae; ventral projection cylindrical, thin, microtrichose throughout; dorsal projection dorsoventrally flattened. Ventral projection of mediobasal lobe about three-quarters length of aedeagus; dorsal projection about three-quarters length of ventral one. Aedeagus cylindrical, with a broad- er base and enlarged at apex; as long as gonocoxite.

Etymology. The specific name is given as a reference to “tereré” or “tererê”, an infusion of yerba mate in cold water of Guarani people origin, typical in South America. The infusion is much appreciated in Mato Grosso do Sul, the type locality of this species. The specific name should be treated as a noun in apposition.
